Firo vs Monero
Both Firo and Monero are leading privacy cryptocurrencies, but they take fundamentally different approaches. Here's how they compare.
Side-by-Side Comparison
| Feature | Firo | Monero |
|---|---|---|
| Privacy Protocol | Lelantus Spark | RingCT + Stealth Addresses |
| Anonymity Set | 65,000+ (global pool) | 16 (ring size) |
| Hidden Amounts | Yes | Yes |
| Hidden Addresses | Spark Addresses | Stealth Addresses |
| Network Privacy | Dandelion++ | Dandelion++ |
| Mining Algorithm | FiroPoW (GPU) | RandomX (CPU) |
| Trusted Setup | No | No |
| View Keys | Yes | Yes |
| Supply | 21.4M + tail emission | Infinite (tail emission) |
| Masternodes | Yes (3,900+) | No |
| Consensus | PoW + LLMQ ChainLocks | Pure PoW |
| Privacy Opt-in? | Default Spark | Always-on |
Privacy Mechanism
Firo uses Lelantus Spark, a "burn and redeem" system where coins are destroyed and recreated without any link to the original. Your coins join a global anonymity pool of 65,000+ burned coins, making statistical analysis essentially impossible.
Monero uses RingCT (Ring Confidential Transactions), which mixes your transaction with decoy inputs from the blockchain. The current ring size is 16, meaning each transaction references 16 possible senders — only one is real.
Key difference: Firo's anonymity set is orders of magnitude larger (65,000+ vs 16), though Monero's always-on privacy means every transaction adds to the decoy pool.
Mining & Consensus
Firo uses FiroPoW, a GPU-friendly mining algorithm with a DAG requirement above 7 GB. It adds a masternode layer (LLMQ ChainLocks) for near-instant finality and strong 51% attack resistance.
Monero uses RandomX, designed specifically for CPU mining. This makes Monero more accessible to casual miners but removes the masternode security layer that Firo benefits from.
Tokenomics
Firo has a capped supply of 21.4 million coins with a planned tail emission to incentivize miners and masternodes long-term. Block rewards are split between miners (25%), masternodes (50%), and the development fund (15%), with 10% to the community fund.
Monero has no hard cap. After reaching ~18.4 million XMR, a perpetual tail emission of 0.6 XMR per block ensures miners are always rewarded, but there is no masternode system.
Transparency & Auditability
Both projects offer view keys for optional transparency — useful for businesses that need to prove income or comply with regulations while keeping the broader public in the dark.
Firo's Spark addresses add a unique advantage: you can publicly share an address for receiving funds while all transactions to that address remain fully private.
Ecosystem & Adoption
Monero is the largest and most widely adopted privacy cryptocurrency, with listings on major exchanges and a large community. It has a strong reputation and wider merchant acceptance.
Firo is smaller but more research-oriented, with protocols (Lelantus) that have been adopted or referenced by other projects. Firo also offers additional features like Spark Assets (privacy-preserving custom tokens) and an upcoming decentralized exchange (FiroDEX).
